Abstract: In the embodiment depicted, the apparatus has a pair of contra-rotating stropping wheels to, and between which successive blades are carried for stropping. A blade-carrier magazine is supported on a rack for slidable translation thereof below a transversingly-travelling blade clamp. A solenoid operates the clamp to cause it to sieze a blade from the therebelow magazine and carry it to the stropping wheels while holding the blade fast. After a blade has been adequately stropped, the clamp returns it to the magazine, to its individual carrier, and displaces a limit stop to allow the magazine to advance and present a next blade to the clamp. The clamp is threadedly engaged with a drive screw, whereby the clamp is moved back and forth between the wheels. Corresponding fore and aft drive clutches, driven by a dual-speed motor, rotate the drive screw, alternatingly, in clockwise and counter-clockwise rotations.

Abstract: The magazine comprises a platform upon which, in slidable disposition, are carried a plurality of blade carriers. The carriers are movable sidewise of the platform, and each such carrier defines a recess in which to nest a blade. The carrier recess is formed of a pair of limbs rising from a base, one of the limbs being integral with the base, and the other being pivotably coupled to an end of the base. The limbs have mutually confronting channels formed therein, with springs set therein, for receiving and latching therein a blade. The pivotable lime is so coupled to the base to allow it to slue and open the recess formed of the confronting channels, so as to release a blade held therein, and to accommodate its closure of the recess by its slueing in the opposite direction to latch and hold a blade in the recess.
